| 英文摘要 | new mesoporous organic-inorganic spheres with trans-(1r,2r)-bis-(ureido)-cyclohexane covalently bridged in the pore wall were prepared by co-condensation of n,n'-bis-[(triethoxysilyl)propyl]-trans-(1r,2r)-bis-(ureido)-cyclohexane and 1,2-bis(trimethoxysilyl)ethane through a hierarchical double templating method. the octadecyltrimethylammonium chloride (c(18)tmaci) and ethanol direct the formation of mono-dispersed hybrid spheres. n,n-dimethyldecylamine, acting as a pore expanding agent, can expand the pore diameter of the hybrid material from less than 1.7-10 nm during the post-synthetic treatment process. the hybrid material was employed as a novel kind of chiral stationary phase for high performance liquid chromatography (hplc. the column packed with the hybrid material with particle size of 6-9 mu m can efficiently separate the r/s-1,1'-bi-2-naphthol enantiomers even at high sample loading and high flow rate because of its high chiral ligand loading (0.93 mmol/g) and high surface area (597 m(2)/g).
